tion.

This invention relates to high-speed rotary motors, and has for its object to provide a rotary motor of the annular-cylinder type, which is hereinafter more particularly described with reference to the accom panying drawings, in which Figure 1 shows in elevation the interior of one of the casings of the motor in which the two annular cylinders for the pistons and the abutment serve as the point for the application of the motive fluid, the latter being considered in the figure in position for exhausting from the annular cylinder to the right and for performing an effective stroke in the annular cylinder to the left. Fig. 2 is a sectional elevation on the line A B of Fig. 1, this latter figure showing all the details of the mtor and among them the three pinions by which the synchronism of movement is assured. Fig. 3 is a section on the axis of the abutment on the line C D of Fig. 1. Fig. 4 is an elevation of the interior of one of the casings of the motor in which the piston-carrying disks are shown ano a plate for covering the abutment. Fig. 5 is an elevation of the abutment shown in the other figures. Fig. 6 is a sectional elevation corresponding to Fig. 5. Fig. 7 is an elevation of one of the extensible crowns employed in the construction illustrated in the other figures, and Fig. 8 is a sectional elevation corresponding to Fig. 7. r

The motor is principally constituted of two casings in which are formed two interrupted annular spaces or cylinders 3 and 4, 5 and 6', of rectangular or other shape, the one beside the other with spaces provided for the rotating abutment, which is secured upon the spindle 9. The cylinders are. separated by the disks 10 and 11, which are mounted on the spindles 12 and 13, respectively. Each disk carries upon each of its faces and upon the same axis two blocks 14 and 15, 16 and 17, of pyramid form, formed of quadrilateral truncate conical shape with the respective opposite lateral facesof curvilinear-shape. These blocks serve as pistons, sliding with slight friction on their three lateral faces in the annular cylinders 3 and 4, 5 and 6 to the section of which they are adapted.

The casings 1 and 2 are provided with sleeves 18 and 19, 20 and 21, 22 and 23-, with stuffing-box caps 24 and 25, 26 and 27 and 28, and flanges 29 30, permitting the mounting and exact closure of the two casings.

Fixed ports 31 32, provided in each casing, serve for the inlet of the motive fluid. These ports open on the other side into the distribution-chambers 35 36 37 38 at the back of the passages 3 and 4, 5 and 6, which chambers are closed by means of covers 39 4O 41 42, which are tightly fixed upon corresponding circular seatings. These chambers are connected to the central nozzles 43 for the inlet of fluid by the ports 44 45. Rotary slide-valves 46, 47 48, and 49 are arranged, respectively, in the chambers 35 36 37 38 to distribute the fluid through the ports 31 32 in the passages 3 and 4, 5 and 6. These slide-valves are fixed directly upon the shafts 12 and 13.

The abutments 7 and 8 are of circular form, Figs. 5 and 6, andcarry each a recess 50 for allowing the pistons to pass. The relative positions of the pistons 14 and 15 and of the recesses 50. and the abutments 7 and 8 are such and arranged in such manner that while the axes of the pistons 14 and 15 in the two annular cylinders to the right 3 and 4 correspond to those of the two recesses of the abutments'7 and 8 the axes of the pistons of the annular cylinders to the left 5 and 6 are exactly in the prolongation of those to the rightthat is to say, thatthe single recess of each abutment allows to pass freely and alternatively in points diametrically opposite the pistons 3 and 4, 5 and 6.

The tightness of the abutments is obtained by the following arrangement:

First. By six groups of cylindrical rods provided with flat faces'51 and 52, 53 and 54,

55 and 56, extending the thickness of the abutments 7 and 8 and mounted in open cylindrical holes upon their periphery. These cylindrical rods are under the action of torsion-springs 57, placed at their extremity, which tend to cause them to pivot upon themself for insuring permanent contact with the abutments 7 and 8.

Second. By two circular expansible crowns 58 and 59, Figs. 7 and 8, carrying a tapered recess 60in their lower part, in which is fitted a wedge-shaped piece 61, capable of longitudinal movement from the exterior by means of a nut 62. Extension-springs 63, placed under the crowns, cause them to press slightly upon the rear face of the abutments 7 and 8,

while the expansibility of the crowns permits of a perfect tightness around their periphery.

The empty spaces 61 of the casings 1 and 2 between the disks 10 and 11 and the abutments 7 and 8 are filled with oil for lubricating the parts of the motor. The coveringplates 66 press, respectively, upon the easings by means of springs, which prevent the oil penetrating into the recesses of the abutments.

In operation it will be understood that the piston-carrying disks of the annular cylinders 3 and 4:, 5 and 6 turn in the same sense and at the same angular velocity. The abutments 7 and 8 turn in acontrary sense, with an angular velocity the same as that of the disks. The synchronism of movement is assured by means of pinions 67, 68, 69, and 70, and the effort of the spindles 12 and 13 is transmitted by the intermediary of the pistons 68 and to the spindle 9, upon which is mounted the pulley 71. While the pistons 14:, 15, 16, and 17 have passed the recesses 50 of the abutments 7 and 8, the ports 72 73 of the rotary Valves 47 49, entering immediately into communication with the fixed ports 31 and 32 of the annular cylinders 3 and 4, 5 and 6, motive fluid passes into the spaces existing between the abutments 7 and 8 and the rear faces of the. pistons 14 and 15, 16 and 17. NVhile the movable ports 7 2 73 of the rotary valves 47 and 19 are nolonger in communication with the fixed ports 31 32 of the annular cylinders 3, 4, 5, and 6, the admission ceases, the expansion of the fluid being effected until the point in which the exhaust-ports 33 and 34 are inclosed, when the motive fluid escapes to the atmosphere or a condenser. At this moment the pistons pass the recesses 50 of the abutments 7 and 8, and, as before. the ports of the rotary valves enter afresh into communication with the fixed ports of the annular cylinders, the motive fluid under pressure effecting the continuous rotary movement, as before described. The introduction of motive fluid into the annular cylinders 3 and 1, 5 and 6 does not take place at the same time. Since the pistons of the cylinders 3 and 4 do not pass the recesses 50 at the same time as the pistons of the cylinders 5 and 6, it follows that while the cylinders 3 and 4; are in the period of exhaust the cylinders 5 and 6 are in the admission period and reciprocal, so that a continuous circular movement without a dead-center is realized.

It will be understood that the motor is not reversible.

hat I claim as my invention, and desire to secure by Letters Patent, is

1. In a rotary motor the combination of two casings which are connected together and are furnished with two series of passages, two disks completely closing the said passages each one being furnished with two blocks or pistons laterally adjusted so as to move in these passages and two obturators the circumference whereof enters the periphery of the fixed portion of the casings at the center of the passages, these obturators being provided with a recess for the passage of the pistons.

2. Ina rotary motor the combination of two casings connected together and furnished with two series of passages in which move lateral pistons carried by a rotary disk keyed upon the motor-shaft and disposed between the two casings, distribution chambers are made at the back of the casings, rotary valves keyed upon the motor-shaft and two obturators placed between the two sets of passages and cutting the central part of the latter, a recess madein each of the two obturators allowing of the' movement of the pistons.

3. A rotary motor comprising two coupled casings in which are provided two series of circular passages and a circular space intersecting the said passages, disks placed between the casings and provided upon each of its opposite faces with blocks or pistons which move into the said passages, obturators placed in the spaces between the casings and provided with a recess for the passage of the pistons and distribution-chambers arranged in the casings in the axial line of the shafts upon which the disks are mounted.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
